General Description
The MagAlpha MA 700 is a robust contactless angle
encoder. The IC detects the absolute angular position
of a permanent magnet, typically a diametrically
magnetized cylinder attached to the rotor. The
MagAlpha is an extremely fast acquisition and
processing sensor, allowing accurate angle
measurement at speeds from 0 to 120’000 RPM.
QFN-16 3x3mm Package
Since the measurement is spatially confined, the user
has flexibility in terms of magnet shapes and
configurations. This can help relaxing mechanical
tolerances and, in case the end of shaft position is not
available, the MagAlpha 700 can also operate away
from the axis of rotation (“side-shaft” mounting).
